This app is using the Proximity sensor of your device. The Proximity sensor is located beside the phone's ear piece.

This app turn on the screen when you wave your hand over the device. Also, you can turn off the device screen by covering the proximity sensor for one second (You can change the amount of time within the app).

Steps​

Open the app.

Enable the app and it will enable both the Wave mode and Pocket mode by default.

Enable the “Lock screen” and provide device administrator permission.

You can check it out other options to customize the app as per your need. Here are the settings I prefer:

To uninstall this app, tap “Uninstall WaveUp” button and the app will do the rest.

There are some things to remember:

Don’t get your device switched off for any reason.

The apps discussed here may consume more battery power.

All the methods discussed above works. But, there is no second thought that they are just the temporary fix.

It’s always good to have your device in the perfect condition. So, I suggest you to take your device to the service center and get it fixed as soon as possible.
